Description

Technical Field

[0001] The utility model relates to the technical field of flat plate filters, in particular to a stainless steel flat plate filter used in the production of pseudouridine series. Background Art

[0002] In industries such as medicine, chemistry, food processing, and scientific experimentation, it is necessary to filter out impurities such as particulate matter, sediment, and microorganisms from large quantities of water, aqueous solutions, or other liquids. A common method for filtering large quantities of liquids is to filter the liquid through a microporous membrane of appropriate pore size. Filtration methods include intermittent natural filtration, continuous pressure filtration, or reduced pressure filtration. Continuous pressure filtration is the most efficient and widely used. The filtration device consists of a pressure pump, a filter, and a filtrate receiver. Flat-plate filters are the most commonly used of continuous pressure filtration devices and are required in the production of pseudouridine.

[0003] A Chinese patent currently published (announcement) with the number CN202321130482.3 discloses a flat filter, including a filter baffle that is detachably mounted on the inner wall of the lower portion of a cylinder. The filter baffle comprises a first filter baffle and a second filter baffle that are hingedly connected, each of which is provided with perforations. The filter baffle of the device is composed of two parts hingedly connected by a hinge. During installation, the baffle can be folded in half and then flattened when it approaches the filter baffle support ring. The same folding is done during removal, making it easier to remove and replace.

[0004] However, there are still the following defects:

[0005] Due to the direct injection of liquid, the instantaneous impact pressure is large and the pressure distribution is uneven, which is very likely to cause damage to the filter screen or filter membrane. Utility Model Content

[0029] This embodiment provides a stainless steel flat plate filter for pseudouridine series production, such as Figure 1-Figure 4 As shown, it comprises: a cylinder 1, a sealing cover 2 is provided on the top of the cylinder 1, a feed port 3 is opened on the surface of the sealing cover 2, a discharge pipe 4 is fixedly connected to the bottom of the cylinder 1, a limit ring 5 is fixedly connected to the cylinder 1, a support plate 6 is provided on the limit ring 5, a filter membrane 7 for filtering liquid in the production of pseudouridine series is provided on the upper surface of the support plate 6, and a decompression component 8 is provided in the cylinder 1;

[0030] The pressure reducing assembly 8 includes a baffle 801, which is fixedly connected to the top of the support plate 6. Overflow holes 802 are evenly opened on the surface of the baffle 801. A pressure ring 804 is provided on the top of the filter membrane 7. A pressure rod 805 is provided on the top of the pressure ring 804. A dispersion block 806 is fixedly connected to the top of the pressure rod 805. A feed pipe 807 is fixedly connected to the top of the dispersion block 806. Discharge holes 808 are evenly opened on the surface of the feed pipe 807. The inner diameter of the feed pipe 807 is the same as the diameter of the feed port 3.

[0031] A stainless steel flat filter used in the production of a pseudouridine series using the above technical solution is provided with a decompression component 8. During the production of the pseudouridine series, the liquid to be filtered is introduced into the cylinder 1 from the feed port 3, and the impurities in the liquid are filtered through the filter membrane 7. The filtered liquid is discharged from the discharge pipe 4. The liquid is decompressed once by the cooperation of the feed pipe 807, the discharge hole 808 and the dispersion block 806. To prevent the liquid from directly impacting the filter membrane 7, the liquid is evenly dispersed and flows in the support plate 6 under the action of the dispersion block 806. The liquid is blocked by the baffle 801. After the liquid overflows the overflow hole 802, the liquid is filtered through the filter membrane 7. The liquid is decompressed multiple times to avoid damage caused by the liquid directly impacting the filter membrane 7. This protects the filter membrane 7, reduces damage and waste of the filter membrane 7, and reduces the cost of use.

[0032] In order to replace the filter membrane 7, a handle 809 is symmetrically provided on the top of the support plate 6, and drainage holes 803 are evenly opened at the bottom of the support plate 6. The drainage holes 803 are provided to drain the liquid filtered by the filter membrane 7 into the bottom of the cylinder 1 and discharged from the discharge pipe 4.

[0033] In order to fix the support plate 6 and facilitate the replacement of the filter membrane 7, a limiting groove 9 is provided on the top of the limiting ring 5, and a connecting ring with the same size as the limiting groove 9 is provided at the bottom of the support plate 6. The connecting ring is inserted into the limiting groove 9 to fix the support plate 6.

[0034] In order to reduce the impact force of the liquid, the dispersion block 806 is arranged in a cone shape, and the maximum outer diameter of the dispersion block 806 is the same as the maximum outer diameter of the baffle 801. Under the action of the dispersion block 806, the liquid is evenly dispersed in the support plate 6.

[0035] To filter the liquid, the diameter of the filter membrane 7 is the same as the inner diameter of the baffle 801, and the sealing cover 2 is placed in contact with the top of the feed tube 807. The sealing cover 2 squeezes the feed tube 807, causing the feed tube 807 to squeeze the pressure rod 805. Under the action of the pressure rod 805, the pressure ring 804 is compressed, thereby tightening and fixing the filter membrane 7.

[0036] In order to better discharge the filtered liquid from the cylinder 1, the bottom of the cylinder 1 is arranged in a funnel shape, and a solenoid valve is provided on the discharge pipe 4.

[0037] In order to prevent liquid from overflowing from the top of the support plate 6, the height of the overflow hole 802 is smaller than the height of the support plate 6, and the baffle 801 and the support plate 6 are both set to stainless steel plates.

[0038] In summary, the stainless steel flat filter used in the production of pseudouridine series provided in this embodiment has the following advantages: a decompression component 8 is provided. During the production of pseudouridine series, the liquid to be filtered is introduced into the cylinder 1 from the feed port 3, and the impurities in the liquid are filtered through the filter membrane 7. The filtered liquid is discharged from the discharge pipe 4. The liquid is decompressed once by the cooperation of the feed pipe 807, the discharge hole 808 and the dispersion block 806. To avoid the liquid from directly impacting the filter membrane 7, the liquid is evenly dispersed and flows in the support plate 6 under the action of the dispersion block 806. The liquid is blocked by the baffle 801. After the liquid overflows the overflow hole 802, the liquid is filtered through the filter membrane 7. The liquid is decompressed multiple times to avoid damage caused by the liquid directly impacting the filter membrane 7. This protects the filter membrane 7, reduces damage and waste of the filter membrane 7, and reduces the cost of use.

[0039] During use, the liquid to be filtered during pseudouridine series production is introduced into the cylinder 1 through the feed port 3. The liquid is then depressurized once through the coordination of the feed pipe 807, the discharge port 808, and the dispersion block 806. The liquid flows out of the discharge port 808 and is evenly dispersed within the support plate 6 by the dispersion block 806. The baffle 801 blocks the liquid. After the liquid overflows the overflow port 802, it is filtered through the filter membrane 7 and discharged from the discharge pipe 4. By depressurizing the liquid multiple times, damage caused by direct impact of the liquid on the filter membrane 7 is avoided. This protects the filter membrane 7, reduces damage and waste of the filter membrane 7, and reduces the cost of use.

[0040] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
